Embodiment 1

[0029] Embodiment 1: as figure 1The shown multi-stage distillation device includes: an electric heater 1, a five-stage condensation distillation vessel 2, an overflow pipe 3 and a distillation vessel 4 whose number matches the condensation distillation vessel 2. The electric heater 1 is connected to the distillation vessel 4, and each condensation distillation vessel 2 is stacked and combined, and placed on the distillation vessel 4; the distillation vessel 4 and each condensation distillation vessel 2 are connected to each other through the overflow pipe 3; 2 is provided with a water inlet pipe 5, and the distillation container 4 is provided with a float type water level control device 8 to control the switch of the electromagnetic valve 20 of the water inlet pipe 5, and the water level control device 8 and each overflow pipe 3 jointly control the water level in each container, That is, the necessary evaporation space is reserved on the top of the distillation vessel 4 and th...

Embodiment 2

[0030] Embodiment 2: as image 3 As shown, it is basically the same as Embodiment 1, except that the heater 1 is connected with the distillation vessel 4, and each condensation distillation vessel 2 is combined side by side, and the distillation vessel 4 communicates with the condensation surface 6 of the primary condensation distillation vessel 2, and the distillation vessel 4 and each The condensing distillation vessels 2 communicate with each other through the overflow pipe 3; a water inlet pipe 5 is provided in the final condensing distillation vessel 2, and a water level control device 8 is provided in the distillation vessel 4, and the water level control device 8 and each overflow pipe 3 jointly control each container The water level in the interior, that is, the necessary evaporation space is reserved on the top of the distillation vessel 4 and the condensation distillation vessel 2; Below, be provided with the sump plate container 7 that matches it.

Embodiment 3

[0031] Embodiment 3: as figure 2 As shown, it is basically the same as Embodiment 1, the difference is that between the distillation vessel 4 and the primary condensation surface 6, and between the condensation distillation vessels 2 at all levels, heat shields 13 are respectively provided, and the heat shields 13 have energy-conducting The orifice 14 for flowing steam not only provides a channel for diverting steam, but also ensures the completion of distillation and condensation, and relies on the heat shield to block conduction heat and radiant heat, which can avoid the gap between the distillation vessel 4 and the primary condensation surface 6, and the The heat conduction and heat radiation between the condensing distillation vessels 2 weaken the heat energy attenuation degree of each stage and improve the distillation effect of each stage.

Abstract

A multi-stage distilling apparatus is composed of a heater, at least one stage of condensing and distilling container, which can be combined to become multiple stages, the overflow pipes whose number is matched with that of condensing and distilling containers, and a distilling container. Its advantages are high distilling efficiency and utilization rate of energy, simple structure, low cost and multiple functions.

Description

technical field [0001] The invention relates to a multi-stage distillation device, in particular to a multi-stage distillation device with sufficient latent heat utilization, high distillation efficiency, desalination of seawater, purification of sewage, and provision of hot water, distilled water and other products. Background technique [0002] The water distiller of Chinese Invention Patent Publication No. CN 2500668Y includes a water storage tank and a distillation device on it, but because the device can only perform single distillation and single condensation, its latent heat utilization and distillation efficiency are all on the low side, and its distillation The cost is also high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage distillation, multiple condensation, full use of latent heat, high distillation efficiency, which can desalinize seawater, p...
